I don't know what possessed me today, but I wrote a little .wav file parser utility on my programming language #badlang and visualize it with raylib.
It's this a sign that my burnout is finally going away? Dunno, but this was a fun little exercise. I forgot how nice it was to write in my little lang, hope I can muster the energy to finish the self-hosting implementation.

Put a bit more work on this. Now it can load multiple samples, display mono/stereo channels as a single sample, and added support for zooming/panning.

Improved the movement look and feel, zooming now uses the cursor position to keep that spot centered when possible. I also added some zero crossing markers that showcases a filled square if it would be safe to splice/play the sample there or not without clicks.

Whoops I made another sampler player.
-
Added some loop/zoom markers and differentiate between looping and not looping modes. When looping, samples start and end on the markers. When not, what you see is what you get. The zoom button focuses the sample range on the region denoted by the markers.
I also went ahead and added sample interpolation to avoid artifacts when the sample rates don't match.

The work continues, big internal refactor today and the addition to starting the oversampling implementation.
I've switched to represent and process everything as stereo samples for simplicity, but display and playback can be switched between mono/stereo regardless of the default.
Finally I added some more info to the cursor and a few extra buttons. Gonna try to do spectral analysis and visualization next.

Lots to do to get here, had to add trig functions and complex numbers to badlang, but I managed to get the naive DFT implementation going. I also added some function generation utilities (sine, DC, impulse, nyquist) so that I can test further experiments on this system.

Finally managed to get the FFT working, turns out I had forgotten how to multiply complex numbers lol
This is fast enough to graph playback audio frames for a real time spectrum viewer. Fun times :)

Some touchups on the spectrum viewer, which now display as log values (dbfs). Added a circular buffer to get some visualization of an oscilloscope and for better fetch data for spectrum visualization in real time.

Had to switch some things around to be able to load long samples, as the performance wasn't great, but now I'm able to move around without issues. Also added a little RMS/Peak meter and dual oscilloscope for the final output.

Added a little Moog style resonant filter. Currently controlling cutoff/resonance with the mouse position. Probably I need to start working on some slider/knob ui elements soon.

Worked on my antialiasing filters and the first steps into controllable knobs.

Got a little sidetracked implemented a simple IMGUI in < 300loc. Very limited at the moment, but it supports buttons, toggleable buttons and regular/bipolar knobs. It's pretty easy to extend too, gonna migrate my previous RMGUI to this soon.

A fresh coat of paint for the GUI, including using my favourite font, Iosevka.
Very pleasant to work with this imgui, should probably switch the sample/spectrum drawing to this system, but for now I'm using a hybrid approach.

@ballalloi che comunque è piú salutare che fumarle, soprattutto se tagli via i filtri prima.

@me is this is a way to give Mozilla more money they can waste on LLM bullshit nobody wants, or does it actually support someone working on actually useful features users actually want?

I just heard that a former classmate of mine passed away. He had a difficult life, he had lost his entire family and, unfortunately, had serious drug and alcohol problems since he was very young. At one point, the situation seemed to have improved, he was working passionately in his business but... I believe that negative spiral had never really left him.
A few months ago my parents saw him and didn't recognize him, he looked like a little old man even though he was about my age. So the news, although terrible, doesn't come as a complete surprise.
What's truly beyond belief, on social media, are the people claiming the vaccine killed him. And I'll stop right there.

Mastodon's new server software (v4.5.0) brings a breakthrough for smaller servers:
No matter which server you are on, all replies to all discussion threads are automatically fetched as soon as you browse a discussion. It doesn't matter which server you are on or which server they are on, you will all see the same complete discussion. (Unless a user or server is banned of course.)
If you've previously held back, this is a great time to try smaller servers! 🥳

@mkj uhm...yes, maybe you're right 😆

@stefano Isn't "pizza" another word for "large sandwich, typically served warm"? 🙂

RE: https://varese.social/@emanuelecariati/115406228081054431
Questo é il primo post che cito. Masto.host ha aggiornato l’istanza alla versione 4.5 👌🏻
Vi aspetto a Varese!

Big News: FreeBSD Joins the Open Container Initiative
FreeBSD has officially joined the Open Container Initiative (OCI), marking an important step in aligning FreeBSD’s long-established jail technology with widely adopted container standards.
This development enables users to begin testing OCI containers on FreeBSD using tools such as Podman.Watch the recent discussion:
https://youtu.be/HV-wUUzRCMo?si=6A-2thWKl2lEbVPXWe welcome your thoughts.
How do you see OCI compatibility influencing your use of FreeBSD?
